Contenido de mercurio en conservas de mejillones, berberechos y navajas comercializados en Galicia (España) L. Loira Torres M. A. García Fernández J. Alonso Díaz M. J. Melgar Riol Química Metal navajas mercurio mejillones berberechos Los moluscos acumulan metales pesados y ponen en riesgo la salud del consumidor. Entre estos metales, el mercurioestá considerado como no esencial y muy tóxico. Se determinó la concentración de mercurio en mejillones, berberechos ynavajas, en conservas comercializadas en Galicia (España). Las porciones de músculo, hepatopáncreas y líquido de coberturase sometieron a un proceso de digestión, en medio ácido, en microondas. El mercurio se analizó por voltamperometría deredisolución anódica con electrodo de oro. Los resultados para molusco completo, expresados en ppm y peso fresco,mostraron los mayores niveles para mejillones (0,27), seguidos de berberechos (0,20) y finalmente las navajas (0,08). Elcontenido de mercurio por porciones fue: hepatopáncreas > líquido de cobertura > músculo. Todas las concentraciones demercurio estuvieron por debajo del límite máximo permitido para consumo humano. Por tanto, su consumo no suponeriesgo alguno para la salud del consumidor. 2007 artículo científico 1135-8122 https://www.redalyc.org/articulo.oa?id=72450509 es http://www.redalyc.org/revista.oa?id=724 Ciencia y Tecnología Alimentaria application/pdf Sociedad Mexicana de Nutrición y Tecnología de Alimentos Ciencia y Tecnología Alimentaria (México) Num.5 Vol.5
